You know you should sleep. But your thumb keeps scrolling. DayLight is a tiny behavior-change tool designed to help late-night scrollers quit staying up too late — without shame, data overload, or complex routines. - Daytime: write a promise to your future self Once a day, DayLight gently asks: “If you don’t stay up late tonight, what do you gain?” Write your own reason or pick from smart suggestions Tap confirm and light up today’s first lamp — a tiny commitment from day-you to night-you - Nighttime: a soft reminder at the decision moment Around your chosen bedtime, DayLight brings back that message: “Day-you left this for you: …” Put your phone down and light the second lamp to complete today’s “light chain” Or keep scrolling — the lamp fades out with a small sense of “what a pity,” not guilt - Light chain: build your streak with kindness Two lamps a day form a simple chain of light Watch it grow as you go to bed earlier, one night at a time Miss a day? No punishment, no shaming — just start again tomorrow - Built on behavior science, not fear or FOMO No complicated dashboards or scary sleep charts No “you failed X days in a row” messages Minimal design focused on one thing only: quitting late nights, gently - Made for modern night owls You scroll, watch, or game yourself past midnight You wake up tired and promise “tonight will be different” You don’t want a full-on life overhaul — you just want to go to bed earlier, a little more often DayLight is where you start. One promise. Two lamps. A kinder path out of late nights.
